Description

The Nortel IP Phone Key Expansion Module (KEM) is a hardware

component that connects to IP Phone 2002 and IP Phone 2004 and

provides additional line appearances and feature keys (see Figure 10 "IP

Phone 2002 with one IP Phone KEM attached" (page 74)).

Up to two IP Phone KEMs can be connected to an IP Phone 2002 or IP

Phone 2004. With two IP Phone KEMs connected, the IP Phone can have

up to 48 additional line/feature keys.

The IP Phone 2004 can also have up to 48 additional line/feature keys

using the Shift key functionality and one IP Phone KEM. With two IP

Phone KEMs connected, the Shift key functionality does not affect the IP

Phone KEMs since the maximum number of line/feature keys is already

available. The IP Phone 2002 does not support Shift key functionality.
